A move to the summer or fall would give visitors a chance to see more of the city in the warmer months.
General Motors has supported a move to June that would possibly correspond with the Detroit Grand Prix. GM North America President Alan Batey this month said such a move would allow for a new automotive spectacle to attract people to the city.
"I just think it could be so much more if the timing was right," Batey told Automotive News. "We could showcase what a great city we've got and what's going on."
